IMPRQVENIBNT IN PIPE-CUPLING-S.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it ma/y conce/m:

Be it known that I, WulLrAM H. YnA'roN, of Ihil-. adelphia, Pennsylvania, have invented an Improved Pipe-Coupling; and I d o hereby declare the following to be a full, clear, and 'exact description of the same.

My invention consists of a device, fully described hereafter, for readily coupling and uncoupling pipes, the said device being especially applicable to the coupling together of pipes used for conveying steam or warm water from carto car of a railroad-train, for the purpose of heating the same.

In order to enable others skilled in the art to make and use myinvention, I will now proceed to describe itsconstruction and operation, reference being had to the accompanying drawing, which forms a part of this spel After separating the twoportions of the coupling,

A has been withdrawmis covered by a lid or bonnet, F, as shown in fig. 4. This bonnet is hinged at s to the portion B, and is intended to prevent the admis sion of particles of dust or other matter to the interior of the pipe.

yoke D upon its pins fn, and prevent it from moving vback beyond the proper point; and the said bonnet, when not in use, is turned down, so as not'to interfere with the coupling of the two portions of the pipe.

On replacing the portions A and B ofthe coupling,-

handle 'is in a position to prevent the movement the said yoke, there is a free passage for fluids through the branch b,- plug O, and interior ofthe branches m' and a.

Although my invention may be applied with advantage to such pipes as have to be frequently. coupled and uncoupled, it is especially applicable to the pipes 'which pass from car to car of a railway-train, for the conveyance of steam'or hot water from the en e or tender o f the train to the several cars, for warming Figure 1 is a sectional view of my improved pipe- Figure 2, an vexterior view ofthe same, showing the mode of coupling and uncouplng;

Figure 3, a plan view; and

Figure 4 a detached view drawn to a reduced scale, and illustrating a portion of my invention.

Similar letters refer to similar parts throughout the several views. urp s.

The coupling consistsof two main portions, A and `rEhe portion A of the coupling may be connected to the flexible pipel of one car, and the portion B tov that of the next car, and when these `cars have 'to be un coupled, all that is necessary is to turn the plug C so as to cut off all communication'betwe'en the pipesof the two cars, then depress the'yoke D, and withdraw the portion A from the portion B of the coupling,

After vreadjusting the portion A to the portion B, and turning the plug to the position shown in fig. 1, the'yoke is, retained in its position by the handle fi, and no` jarring of the cars can cause the disconnection of the portions of the coupling.

I claim as my invention, and desire to. secure by Letters Patent- 1. The combination of the portions A and B of the coupling with the yoke D, the whole being constructed and arranged substantially as and for the purpose described.

2. The plug O, adapted' to the .portion Bof the coupling, and having a handle, i, arranged in respect to. the yoke D, substantially as set forth.

3. The combination, with the yoke D, of a lid or bonnet, F, having lugs t t, and hinged or otherwise adapted to the portion B of the coupling, for the purpose specified.

In testimony whereof, I have signed my. name to this specication in the presence of two subscribing witnesses.

WILLIAM H. YEA'ION.

a pip and the latter a branch, b, towhich is secured another similar pipe,

Into the portion B of the coupling is fitted a tapering plug, C, having a transverse opening, c, which, when the plug is 1n the positlon seen m fig. 1,. forms a continuation of the interior of the branch b, the plug being packing-ring f. The plug has a projecting stem, h, and a handle, i, which will be referred to hereafter.

The por on A of the coupling has a hollow branch, fm, cylindrical or slightly taperin and arranged at right angles to the branch a, and this branch m fits snugly 1n a chamber formed in the portion B of the coupling, to which the portion A is confined by a yoke, D, A.which passes over the portion B, and is hinged thereto by set-screws n, the yoke bearing at a;,-iig. 1, on the portion A, between which and the portion B intervene two suitable packing-rings, q and q.

The handle i is of such a length, and so arranged in respect to the opening c of the plug O, that when the latter forms a continuation of the interior of the branch b, as shown in fig. 1, the said handle will prevent the depression of the yoke.

When the plug'is turned at right angles to the position shown in iig. 1, and intercepts the communication of the interior of the portion B of the coupling with that of the portion A, the yoke D can be turned downwards, to the position shown by red lines, fig. 2, and Iliitns'esses:v the portion B of the coupling can then be readily with- E.
